Regualr Expression跳过空白 [英] Regualr Expression to skip white space

问题描述

我正在使用正则表达式从字符串中检索数据.
我有一种情况，逗号分隔符后可能有空格，也可能没有空格
我该如何处理.

例如:

"myName，age"在年龄之前存在一个空格，但是有可能我可以得到没有该空格的相同字符串，例如"myName，age".如何使用相同的正则表达式处理这两种情况.
请提前告知谢谢

I am using regular expression to retrieve data from a string.
i have a scenario where in there may be or may not be white spaces after comma seperator
how shall i handle this.

for eg:

"myName, age" here before age there is a white space but there are chances i can get the same string with out white spaces like this "myName,age" . How shall i handle both cases using same regular expression.
please advise thanks in advance

推荐答案

如果您只想将它​​们分开，为什么要使用正则表达式而不使用split函数:

If you want to just separate them why using regular expressions , and not using split function :

string s = "myName  ,   age  ";
List<string> fields = s.Split(',').ToList();
for (int i = 0; i < fields.Count; i++)
{
    fields[i] = fields[i].Trim();
}

您可以将带有"\s*[,]\s*"的逗号识别为RE模式，但是我认为Split 函数可以解决您的问题.

希望对您有所帮助.

You can recognize commas with "\s*[,]\s*" as the RE pattern but I think that Split function will solve your problem.

Hope it helps.

为您的方案尝试以下RegEx代码:

Try the below RegEx code for your scenario:

Regex regexObj = new Regex(@"""[^""\r\n]*""|'[^'\r\n]*'|[^,\r\n]*");
